Telescoping power medium

Telescoping power medium description/claims

This Application is a division of U.S. patent application Ser. No. 11/706,160 filed Jul. 21, 2006.

Not applicable.

Not applicable.

The invention relates to a telescoping power medium. The invention is further directed to a light fixture that has a telescoping arm.

Track or rail lighting fixtures suspended from ceilings are usually hung from the track via fixed length lighting fixtures. Once attached, if the height of the light fixture is to be adjusted, the lighting fixture must be removed and a new lighting fixture of a different height must be placed on the track, assuming the consumer has multiple fixed length lighting fixtures available. The inconvenience of disassembling the light fixture, changing the light fixture and reattaching the light fixture to the track warrants a mechanism that would simplify the adjustment of the height of the light fixture. This inconvenience would also be applicable to any situations where a power medium provides power remotely from the power source.

Some track lighting fixtures do not allow the light source to be directed in more than one direction for the purposes of art or trade displays. The ability to direct light from either the base of the light fixture or the light fixture would be advantageous to those in the lighting arts. To be able to tilt, swivel or pivot the light without moving the track and/or fixtures would make it easier to set up and break down displays.

Current track lighting telescoping fixtures utilizes two arms wherein each arm acts as a conductor, or a single arm acting as one conductor, and an external or internal wire acting as a second conductor. The use of two arms minimizes design and aesthetic flexibility. The use of either an internal or external wire complicates or prevents telescoping ability.

Embodiments of the invention include a telescoping power medium having a first end and a second end. The first end of the medium is attached to a power source and the second end of the medium is attached to a power receiver. The telescoping power medium can be telescopically positioned at any one of several distances and has an outer collapsible conductor surrounding an inner collapsible conductor.

A preferred embodiment is a light fixture having a lighting track; a base coupled to the lighting track; a lamp housing coupled to the base; and a telescoping arm. The arm has a first end attached to the base and a second end attached to the lamp housing. The telescoping arm allows the lamp housing to be telescopically positioned at any one of several distances from the base. The telescoping arm comprises an outer collapsible conductor surrounding an inner collapsible conductor. The lamp housing may pivot from 0 to 90 degrees relative to the telescoping arm. The lamp housing may be 360 degrees rotatable around the axis of the base. The outer collapsible conductor may be a conductive material or a low voltage material. The inner collapsible conductor may be a conductive material, such as but not limited to, aluminum, tin, copper, steel, or any alloy. In a preferred embodiment, the inner collapsible conductor is brass. There may be insulation between the inner collapsible conductor and the outer collapsible conductor. The lighting track supplies power to the light housing via the base and the telescoping arm. The lamp housing also includes a light bulb which may be a line voltage, low voltage incandescent, halogen, xenon, fluorescent, metal halide, high and low pressure sodium or LED bulb.

An alternative embodiment is a telescoping light fixture arm having a first end and a second end. The first end of the arm is adapted to electrically connect to a lighting track and the second end of the arm is adapted to electrically connect to a lamp housing. The arm comprises an outer collapsible conductor surrounding an inner collapsible conductor. The telescoping arm allows the lamp housing to be telescopically positioned at any one of several distances from the base.
